This new seat is based on the whole of the former Dunfermline West constituency. Rosyth and Inverkeithing in the southeast are the only large population centres on the coast. To the north and west of Dunfermline is more rugged and robust Fife countryside. The whole seat is up against the Firth of Forth.

The subsequent by-election was held on 9 February 2006, which Liberal DemocratWillie Rennie won in a shock defeat for Labour. The Liberal Democrats also gained the Dunfermline West Scottish Parliamentary constituency from Labour in the 2007 Holyrood Parliament elections.
